Abstract Large lecture classes and standardized laboratory exercises are characteristic of introductory biology courses. Previous research has found that these courses do not adequately convey the pro...

Genome-wide studies have identified certain single-nucleutide polymorphisms (SNPs), mutations at specific points in the DNA, that increase a person’s risk of developing cancer. Yet, research so far has shown that most SNPs likely only have a modest effect on risk. In the 7 December issue, Sur et al. used a mouse model to look at the functional impact of a particular SNP linked with cancer risk. Mice with this mutation developed intestinal tumors, and when the mutation was deleted, mice displayed fewer tumors. This study suggests that this specific SNP may play a causal role in human cancer.

It’s a sad but familiar scene near the grounds of many medical campuses: hospital-gowned patients, some toting rolling IV poles, huddled in clumps under bus shelters or warming areas, smoking cigarettes.Smoking causes 30 percent of all cancer deaths and 87 percent of all lung cancer deaths. Yet, roughly 50 percent to 83 percent of cancer patients keep smoking after a cancer diagnosis, through treatment and beyond, says Sonia Duffy, a researcher at the University of Michigan School of Nursing.http://www.futurity.org/health-medicine/why-patients-with-cancer-don%E2%80%99t-quit-smoking/﻿

Many internet commenters – and occasionally, random people at parties – think there's a global conspiracy among cancer researchers to suppress 'the cure' as a get-rich-quick scheme. Let's discuss how silly that is
